The basic issue you seem to be overlooking is that for an active passive switch to function truly, to allow the bass to run fully passive without battery operate components, like the new fender preamp does, you MUST have passive pickups (EMG selects are passive pickups made by EMG but all other EMG pickups are 100% active) otherwise you're active pickups, which run off a battery, will not produce any sound when the switch is used. Here lies your first issue.
this can be overcome easily with a different choice in pickups.
What sound are you after as EMG's are nice but if you want a sound achievable from other manufacturers and are so dedicated on having an active passive switch then I would recommend a different set of P/J pickups, perhaps Dimarzio or Delano.
On a similar point, I cannot say for certain but I know that almost all preamps are designed for passive pickups and will not work with active ones, as far as I know EMG make preamps for their pickups and Audere has an option for use with active pickups but, I severely doubt that a bartolinin preamp will function with EMg pickups.
My suggestion to you would be to research a different set of P/J pickups, there are plenty of amazing pickups out there in this configuration and a quite TB search will find you a lot of threads about which is best etc.
THEN if you decide to stay with EMG pickups you've got to let go of your active passive capabilities as these aren't possible with true active pickups.
OR you can have passive pickups and look into the preamps with the control layout and configuration you desire. A few recommendations for you of preamps that have or allow active passive switching in several configurations:
-John East U retro preamps - I have the deluxe 5 in a bass and it is a wonderful unit with great true passive running as well as a very useful and extensive active tones. Highly recommended and lots of options.
-Bartolini preamps- These can be configured and have a passive switch added in by the manufacturer so should fit your requirements. Great preamps too and have worked well when I've had them in basses. Their pickups are also worth a look, I love mine.
-Nordstrand Preamps - Very flexible as to how they're configured and allow for full active passive working with tone controls and push/pull pots for most switches so they look very clean and minimal but are very very powerful and highly acclaimed units. Also check out their pickups, everyone on TB seems to love them and I really want to try them.
-Audere Preamps - They have 2 types of preamps, both of which can be as extensive or simple as you want, you literally pick which controls you want or don't want. They have active passive switches as an option and seem quite affordable or such a high end custom unit. But I have no experience with them so can only recommend them on what I've heard on here.
Then there's plenty of other lesser known/used (by me at elast) companies such as MEC, Delano, Basslab, Glockenklang, Artec and many others I'm sure.
I hope this has helped in some way, feel free to ask questions but I'm not an electronics guru just a guy who likes basses and wants to help you get a good one going. Those new USA deluxe models do look amazing.
